# Question

If 23 percent of all patients with high blood pres–sure have bad side effects from a certain kind of medicine, use the normal approximation to find the probability that among 120 patients with high blood pressure treated with this medicine more than 32 will have bad side effects.

If the probability is 0.20 that a certain bank will refuse a loan application, use the normal approximation to determine (to three decimals) the probability that the bank will refuse at most 40 of 225 loan applications. With reference to Exercise 7.9, find the probability distribution of the random variable Z = (X – 1)2. Exercise 7.9 If X has a hypergeometric distribution with M = 3, N = 6, and n = 2, find the probability distribution of ...If the probability density of X is given by Find the probability density of Y = X3. Also, plot the graphs of the probability densities of X and Y and indicate the respective areas under the curves that represent P(1/2 < X < ...If the joint probability distribution of X and Y is given by f(x, y) = (x– y)2 / 7 for x = 1, 2 and y = 1, 2, 3, find (a) The joint distribution of U = X + Y and V = X – Y; (b) The marginal distribution of U.
